I have built an antenna analyzer (AA-908) that reports SWR, complex
impedance, capacitance and inductance. It works fine with coax-fed resonant antennas. How can I use it to test a 40M double zepp with 300 ohm twinlead feedline? I am at this point interested in finding the frequencies in 160M band at which this antenna and particular-length feedline will propagate. Needless to say, I see maxed out numbers almost all the time (SWR10 and impedance 600). Should I use a balun? Is there something I can use (like a 50 ohm resistor in parallel) that will give me numbers that I can use? What should I be looking for? Ken KC2JDY Ken (to reply via email remove "zz" from address) |
